background: epidemic and endemic cholera is a major public health problem for many   countries. aim of this study was to evaluate ap-pcr for investigation of clonal relatedness among the strains of vibrio cholerae recovered from an out­break occurred in different parts of iran in 2005. methods: the study was conducted during the cholera outbreak occurred in some of provinces in iran in summer 2...

ten field isolates of mycoplasma gallisepticum (mg) from different geographical areas of iran were analyzed by random amplification of polymorphic dna (rapd). rapd analysis produced reproducible banding patterns on the basis of which various distinct amplification patterns could be detected. mg isolates compared with reference strains (s6 and mg ss) and vaccine strain (ts-11) and demonstrated d...

Molecular biology laboratories frequently face the challenge of aligning small overlapping DNA sequences derived from a long DNA segment. Here, we present a short program that can be used to adapt Excel spreadsheets as a tool for aligning DNA sequences, regardless of their orientation. The program runs on any Windows or Macintosh operating system computer with Excel 97 or Excel 98. The program ...

The aim of this paper is to show how teachers can use Visual Basic language on the spreadsheet for student sin order to gain the skills need in using nonparametric techniques for density and regression function estimations. The author has built a useful didactic tool on Excel Visual Basic for teaching and practice of nonparametric kernel methods, being intended for students with some preliminar...

Bessel beams are widely used in optical metrology mainly because of their large Rayleigh range (focal length). Radial/azimuthal polarization of such beams is of interest in the fields of material processing, plasma absorption or communication. In this paper an experimental set-up is presented, which generates a Bessel-type vector beam with a spatial polarization, oscillating along the optical a...

Abstract The objective was to determine the effects of multi-carbohydrase Rovabio Advance on growth performance, mortality, and morbidity wean finish pigs. In trial, 1,260 DNA weanling barrows were fed from 5.9 kg 133 live weight. Four diets fed: positive control (PC), low nutrient density (LNDC), PC with (PC+), LNDC (LNDC+). compared contained 41 Kcal/kg less NE 0.012% SID lysine. Positive 1.3...
